2. Continuous Glucose Monitoring (CGM): Revolutionising Diabetes Care
Key Features & Developments:
Devices such as the FreeStyle Libre 3 and Dexcom G7 enable continuous glucose monitoring (CGM) without the requirement of frequent finger pricks, significantly enhancing the quality of life for individuals managing diabetes.
Subcutaneous CGM sensors provide real-time blood glucose readings, enabling users to make informed dietary and medication-related decisions.
AI-driven predictive analytics are now capable of forecasting glucose fluctuations before they occur, thereby mitigating the risk of hypoglycemia or hyperglycemia-related complications.
Seamless integration with smartphone applications and wearable devices allows for comprehensive tracking of glucose trends over extended periods.
The emergence of non-invasive CGM technologies that utilise sweat or interstitial fluid analysis, rather than traditional skin-penetrating sensors, is on the horizon.
Indian Context:
With India reporting one of the highest diabetes prevalence rates globally, CGM adoption is accelerating among patients and healthcare practitioners.
Startups like BeatO are pioneering affordable CGM solutions tailored to the Indian market.
Healthcare institutions across India are leveraging CGM data to optimise telemedicine consultations and improve patient outcomes.
